Mobile Terminal and Controlling Method Thereof

1. A mobile terminal, comprising: a wireless communication unit; a display unit configured to display a screen including information about at least one audio data; an audio output unit configured to output the at least one audio data; a memory configured to store a plurality of contact information of at least one correspondent party, the plurality of contact information including at least one voice feature vector value for recognizing a voice of the at least one correspondent party, respectively; and a controller configured to: analyze a voice feature vector value of the at least one audio data, search the memory for at least one contact information including a specific voice feature vector value matching the analyzed voice feature vector value, and control the display unit to display the searched contact information.

2. The mobile terminal of claim 1 , wherein the at least one audio data is included in a website screen, a music play screen, or a video play screen.

3. The mobile terminal of claim 2 , wherein the at least one audio data included in the website screen includes a voice post of the correspondent party, a voice replay of the correspondent party, or a UCC (user created contents) video including a voice of the correspondent party.

4. The mobile terminal of claim 1 , wherein the analyzed voice feature vector value is a voice feature vector value of a voice directly recorded by the correspondent party, a voice feature vector value of a voice recorded in the course of a call with the correspondent party, a voice feature vector value of a correspondent party's voice extracted from a currently played music file, or a voice feature vector value of a correspondent party's voice extracted from a currently played video file.

5. The mobile terminal of claim 1 , wherein if the memory does not include the specific voice feature vector value matching the analyzed voice feature vector value, the controller accesses a web via the wireless communication unit and then searches the accessed web for the contact information including the specific voice feature vector value matching the analyzed voice feature vector value.

6. The mobile terminal of claim 1 , wherein if a specific contact information among the displayed contact information corresponding to a specific contact is selected, the controller controls the wireless communication unit to connect to the specific contact.

7. The mobile terminal of claim 1 , wherein the controller controls the display unit to display at least one icon indicating the searched at least one contact information including the matching voice feature vector value.

8. The mobile terminal of claim 7 , wherein the controller combines at least one image corresponding to the searched at least one contact information that includes the matching voice feature vector value, with the at least one icon displayed on the display unit, and then controls the display unit to display the combined at least one image with the at least one icon, respectively.

9. The mobile terminal of claim 8 , wherein, while the at least one image is displayed, the controller controls the display unit to display the at least one icon next to edges of the at least one image, respectively.

10. The mobile terminal of claim 1 , wherein if a plurality of contact information of different types is stored in the memory, the controller controls the display unit to display icons indicating the different types of the plurality of contact information.

11. The mobile terminal of claim 9 , wherein the controller controls the display unit to display the icons on facets of a rotatable 3D polygonal shape, respectively.

12. The mobile terminal of claim 9 , wherein a function including a call function, a message send function, an email send function, a homepage access function, or a blog access function is assigned to each of the icons.

13. A method of controlling a mobile terminal, the method comprising: displaying, via a display unit of the mobile terminal, a screen including information about at least one audio data; outputting, via an audio output unit of the mobile terminal, the at least one audio data; storing, via a memory of the mobile terminal, a plurality of contact information of at least one correspondent party, the plurality of contact information including at least one voice feature vector value for recognizing a voice of the at least one correspondent party, respectively; analyzing, via a controller of the mobile terminal, a voice feature vector value of the at least one audio data; searching, via the controller, the memory for at least one contact information including a specific voice feature vector value matching the analyzed voice feature vector value; and displaying, via the display unit, the searched contact information.
